HI,<br>     <br>I&#39;m trying to scale out a openldap server deployment to serve around 100K users.  I plan on having a master server and using syncrepl to create slaves that sit behind a load-balancer.  Is there a good rule of thumb to abide by when creating a scenario like this?  How many authentications/sec can a server typically handle?  I&#39;ve seen the  benchmark comparisons (<a href="http://www.usenix.org/event/lisa07/htgr_files/chu.pdf">http://www.usenix.org/event/lisa07/htgr_files/chu.pdf</a>) that have been posted by Howard, but it doesn&#39;t say what the system specs were that the tests were performed on?  I will have pretty beefy systems to use (lots of RAM and CPU)...<br>

<br>Thanks!!<br>
